It took only 3 months and 11 days after CST acquisition to Flomerics EM business line for ANSYS a global innovator of simulation software and technologies designed to optimize product development processes to acquire Ansoft Corporation, a global provider of Electronic Design Automation (EDA) software. According to a press release from both sources, parties has signed a definitive agreement whereby ANSYS will acquire Ansoft for a purchase price of approximately $832 million in a mix of cash and ANSYS common stock.

An action from Ansoft side was expected since the acquisition of Flomerics by the closest competitor to Ansoft which strengthens CST position in EM business over Ansoft. As president and CEO of Ansoft, Dr. Csendes puts it “The combination of Ansoft’s extensive portfolio of electromagnetics, circuit and systems simulation solutions with ANSYS’ existing simulation capabilities creates a ‘best of breed’ company that will continue to lead the evolution and innovation of engineering simulation by enabling customers to improve their product development processes, eliminate physical prototypes, reduce time-to-market for new products and improve product innovation and performance,” who will join ANSYS’ Board of Directors following the closing of the transaction.

Early this morning Computer Simulation Technology (CST GmbH) announces the acquisition of the Flomerics electromagnetics simulation software business (EMLOB) including MicroStripes and FLO/EMC with effect from January 1, 2008.

This acquisition will add an alternative Time Domain solver technology (TLM method) to the list of Microwave Studio solvers. You can check our study of the different EM solver techniques on the market.
Furthermore, Flomerics’ strong position in the EMC market and related specialised product features will offer new possibilities to CST’s users, also operating in this market.

“Flomerics has decided to focus on maintaining its leadership position in electronics thermal analysis and growing its market share in general-purpose CFD,” commented Gary Carter, Chief Executive of Flomerics. “We chose to sell the business to CST to ensure first-class ongoing support and the commitment to providing the best tools in the business for electromagnetics simulation.”

This acquisition is more likely a strategic cooperation between Flomerics and CST. Customers will benefit from using a combination of world-leading analysis software products from the two companies. As for current MicroStripes and FLO/EMC customers, they will continue to receive full technical support from CST.
Flomerics and CST have been struggling to increase their share in the EM market, perhaps through this acquisition and by combining their knowledge and enlarging the user base, CST Microwave Studio will manage to beat Ansoft HFSS.

“The acquisition of the Flomerics EM business line and its TLM technology follows CST’s strategy of providing the most complete technological offering for the high frequency EM market,” said Dr. Bernhard Wagner, Managing Director, CST. “We will ensure a high level of continuity for all users of the MicroStripes and FLO/EMC products and are looking forward to working closely with all customers.”

It is always a tough decision when it comes to buy a new product. Several factors come into question: Technical properties, Usability and Cost. Of course, these factors could be arranged in different order depending on ones priorities. Today’s topic is Handheld spectrum analyzers.
For those who are not familiar with the “handheld” term, a handheld spectrum analyzer provides RF engineers and service technicians with the excellent performance of a workbench analyzer in a portable form.
Here’s a detailed comparison between the top handheld spectrum analyzers on the market. The different models are compared one on one for each property in the different categories, from RF performance (technical point of vue), Interface platform (usability) to Commercial (cost).
